Can someone tell me what this tube and splitter assembly’s part no./name is? I had to replace my starter and this tube has disappeared in the process :/

 

I don't have the part numbers for these but do not waste your time and money at Lexyota for this, you're going to get ripped off. Get plain ol' vacuum hose and a splitter at your local auto parts store. I recall that ball shaped plastic piece below the splitter is either an adjustment or check valve.

When I had my RX330, I replaced all of mine due to age and skipped Lexus entirely with no issue. Just make sure the hose is the same diameter. You can test by plugging it into the nipple at the air box.

 

i agree with the above; instead of just replacing the one hose u are better off replacing all of them as they are fairly inexpensive to replace and it just makes sense while yer replacing one to do all of them. Like has already been said; u should be able to get them at any auto parts store(napa, oreilys, autozone, etc) just make sure they are the same size and will fit the nipples on the end of the airbox and the t adapter next to the airbox that the lines connect to. just be careful of one small thing; if u forget to connect all of them you might end up getting a check engine light(cel)

 

Agree with others that local auto parts should have it. Should you decide to go OEM, even though it isn't called out, the hose should be the same as 90999-92002 (see pic). You can cut to length.
